[Product Introduction]

  This product is a colloidal gold rapid detection card used for qualitative detection of Karen,Laike,and Sardine residues in animal urine.The entire detection process only takes about 3-5 minutes.The sensitivities of Karen,Laike,and Sardine are 3ng/ml(3ppb),3ng/ml(3ppb),and 5ng/ml(5ppb),respectively.
  Product composition
  Klein,Lake,and Sardine Immunocolloidal Gold Rapid Detection Card(50 pieces/box)
  Dropper(1 piece/bag)
  Desiccant(1 piece/bag)
  Sample processing
  Collect approximately 50ml of urine using a dry and clean centrifuge tube or appropriate container.If not tested immediately,urine samples can be stored for 24 hours at 2-8℃refrigeration,and attention should be paid to avoid spoilage,which may cause failure or contamination.When a positive result appears,the sample should be packaged in bottles according to the legal procedure for confirmatory testing.
  [Usage Steps]
  1.Before conducting the test,read the user manual thoroughly and restore the test card and sample solution to room temperature before use.
  2.Remove the testing card from the original packaging bag and use it as soon as possible within one hour after opening.
  3.Place the detection card flat,use a dropper to draw the solution of the sample to be tested,and vertically add 2 drops into the sampling hole.After adding the sample,start timing.
  4.The result should be read within 3-5 minutes,and interpretation at other times is invalid.Determine the result based on the schematic diagram.
  【Result judgment】
  S negative(-):Two purple red bands appear.Indicates that the sample does not contain the analyte or its concentration is below the sensitivity value.
  Positive(+):If there is no color development in the T-line,it indicates that the concentration of the substance to be tested in the sample is higher than the sensitivity value.
  Invalid s:No quality control C-line appears,indicating incorrect operation or detection card failure.
  [Example of results]
  【Precautions】
  1.Please use the testing card once within its shelf life;
  2.Avoid direct sunlight and direct fan blowing during testing;
  3.Try not to touch the white film surface in the center of the detection card;
  4.Urine droppers should not be mixed to avoid cross contamination;
  5.If there is sediment or turbidity in the urine sample,please centrifuge before testing;
  6.Please contact the supplier for any issues encountered during the experiment.
  7.If you need to directly test the standard,please prepare it with mixed negative pig urine.
  [Storage and expiration date]
  The original packaging should be stored at 4-30℃,in a cool,dark,and dry place,and should not be frozen;The validity period is 24 months.The expiration date and batch number can be found on the outer packaging.
